Pedigree Analysis
Liddlehome Resur Lu first caught our eye as an 8 year old at the All-American show in 2017. She stood out from the crowd with her overall balance. She was more moderate in stature and had considerably more width and dairy character than the type of cows that we typically see at shows. She was very structurally correct in every way. She had a tremendous leg, beautiful mammary, level rump, deep sprung rib, and a harmonious blending of parts from her head to her tail.
We continued to watch Lu develop, impressed with just how well she kept maturing into a more and more impressive individual. Eventually she joined the coveted and rare EX-97 club! It was obvious to us that we needed to get a son from her. After some deliberation, we made a contract with Liddleholme with a mutually agreed mating of Atlanta-P and Advent-Red as the sires of choice.
Unfortunately before Liddleholme was able to fulfill the contract, Lu was diagnosed with cancer at almost 13 years old and had to be put down. Although we were disappointed that our contract couldn’t be fulfilled, we were presented with another option. Paul Skarka, from NY, had been selling semen from Lu-Tenant-Red, Lu’s Army son. We feel that Army was a good mate on Lu and we are very excited to add Lu-Tenant-Red to the roster at Triple-Hil Sires. Lu-Tenant’s oldest daughters are about breeding age. We expect them to follow the “Lu” pattern of moderate size, stature and slower maturing.

comparable PTAT bulls
305-AA is the standardized milk, fat, and protein yield estimate used by CDCB to compare cows of different ages, parities, breeds, and regions on equal footing. According to CDCB and USDA AGIL, it represents “a 305-day lactation record at 36 months of age” — hence “Average Age,” or AA.
It replaced 305-ME (Mature Equivalent) in June 2024 for published records and was implemented in the calculation of CDCB genetic evaluations effective August 13, 2024. ME had been the standard since 1935.
How it is calculated
The new factors are applied as a series of separate multipliers for age-parity, season, previous days open, and milking frequency. Lactation records are adjusted upward or downward to what the cow would have been expected to produce as a 36-month-old, milked twice daily for 305 days.
Key adjustments include:
- Age-parity: Standardized to 36 months rather than ME’s mature range of 61–86 months depending on breed.
- Season/climate: Seasonal effects are now estimated within five regions defined by the average climate zone scores for each state, replacing the old three east-to-west geographic regions.
- Milking frequency: Still standardized to 2x milking, unchanged from ME.
- Previous days open: The methodology for this adjustment is also unchanged from ME.
